BP is to hand over its detailed framework agreement with Rosneft to its
Russian partners in TNK-BP in a last-ditch attempt to avoid legal action.

TNK-BP's Russian shareholders – Alfa Access Renova (AAR) – have claimed that BP's deal with rival Rosneft to develop oil fields in the Arctic breached its existing agreement with BP and have threatened to take BP to court.

BP announced its "strategic alliance" with state-owned Rosneft last month. As part of the deal Rosneft and BP "swapped" £5bn-worth of shares.
